Synastry contact

Moon Conjunction Jupiter Synastry: When How One of You Feels Meets What Widens the Other's World

Short answer: Moon conjunction Jupiter synastry (comparing two birth charts) means that how one of you feels and what widens the other's world, such as encouragement, generosity and growth, fall in the same place in the zodiac. The two usually share a sign, so the contact can read as fusion or mirroring: the way one of you is encouraged and the way the other feels at ease may turn out to be much the same thing. Two older books, Simmonite's and Wilson's, put Jupiter on the place of a Light (the Sun or the Moon) among the greatest sympathies and the best signs of attachment they describe, in passages that name the Lights together. It is one contact among many, and what gets built on it is up to the two of you.

How you feel meets what widens the world

Every birth chart has a Moon and a Jupiter, and they do different jobs. The Moon is how you feel: your moods and needs, the habits that comfort you, what it takes for you to feel settled. Jupiter is what widens your world: the encouragement you give and receive, your generosity, your appetite for learning and trying things, the sense that there is room to grow. In this contact, one person's Moon falls at, or very close to, the same point of the zodiac as the other person's Jupiter: about 0° apart.

Two points in the same place usually share a sign, and so they share an element (fire, earth, air or water) and a way of going about things. (Usually, not always: a conjunction that starts near the edge of a sign can reach into the next.) That is the geometry. The reading built on it is fusion, or mirroring. The kind of thing that makes one person feel at ease and the kind of thing that makes the other person's world feel larger may be the same kind of thing, so a good idea and a comfortable evening can turn out to be one event.

Any pair can have it: friends, siblings, colleagues, flatmates, a parent and their child, partners. It is only one of many contacts in any two charts.

Who is who in this contact

In this contact one of you brings the Moon and the other brings Jupiter, and the two are in the same place. Call them the Moon person and the Jupiter person.

If you are the Jupiter person, you are mostly just being the way you are with the world: saying "go on, try it", passing on the spare ticket, thinking of a bigger version of the plan. What you may not notice is how readily your enthusiasm can sit alongside the other person's feelings. They do not have to be talked round to it, and your generosity may arrive in a size and a style their mood can take.

If you are the Moon person, it can feel as if someone else's encouragement already fits you. The invitation comes when you were ready for one, and the idea is expressed in words you might have chosen yourself. You may find your mood opening up around them, and afterwards not be able to say whether it was them, the idea or the hour.

If the link also runs the other way, from the Jupiter person's Moon to the Moon person's Jupiter, each of you is both.

What each gives, and what each may want

Either of you may be the one who offers kindness and the one who receives it, and in a conjunction the two jobs can look much alike.

One thing this contact can give is encouragement that arrives in a form the feelings can take: a nudge toward something new that suits the temperament of whoever receives it. Another is a response that is easy to read. Interest or ease shows, and may tell the one who offered that the offer was welcome.

Either of you may want your goodwill taken as real and not only accepted. Either of you may want your feelings kept in view while plans grow, and room to say "not yet" to something you otherwise like.

Decisions, disagreements and ordinary evenings

As the two of you share a place, a decision about something new may feel easy to make together. One of you floats an idea and the other may find they were already leaning that way, so the choosing can take less talking than usual. That can be a pleasure in itself.

A disagreement may look different too. Where the two of you are in the same sign, you can want the same thing at the same moment, and what you argue about is who gets it, or when, not which thing it should be. The disagreement can also be quiet: each of you may suspect the other of having the same doubt, and neither says so first.

An ordinary evening may be spent in a way that suits both of you with no arranging: the same programme, the same walk, the same decision to stay in. It describes how things can feel when one person's comfort and the other's wider interests are in one place.

How it might look

These are sketches, not reports: illustrations of how the contact might show up across different kinds of pairs.

Colleagues. One colleague mentions a beginners' birdwatching morning coming up in the autumn. The other, who has not looked at a new course in years, signs up the same night and gets to the first class a little early.
Parent and child. A child is nervous about a swimming trial. Their parent drives to the pool the day before, only to look at the changing rooms, and the child finds the trial feels smaller afterwards.
Siblings. One sibling sends the other a folded map with a coastal path marked in felt tip and no message. The other leaves it on the fridge for a month before booking.
Friends. One friend brings a shy friend to a drop-in print-making workshop. Neither mentions it again, and both are inky to the elbows by the third week.
Neighbours. One lends a wheelbarrow and stays for an hour to talk about the shed roof the other has been unsure about. The roof is not decided, but it is now a plan.
Partners. One partner makes a list of walks for the spring. The other, who had been quiet, reads it twice and starts marking the ones they would pick.

In each sketch one person opens a door, and the other person's feelings are already facing it.

In fire, earth, air or water

A conjunction usually keeps to one sign, so the element of that sign can shape the feel of the contact. In plain terms: fire is enthusiasm and action, earth is practical steadiness, air is talk and ideas, water is feeling.

Fire. Both may share a quick warmth, so excitement and comfort can arrive together. It might look like two friends who decide on a Friday afternoon to try the climbing hall, and are both in better spirits by the time they have their shoes on.

Earth. Both may trust what they can see and handle: a good plan, a sound tool, a thing built to last. It might look like a grandparent and grown grandchild who spend a Saturday painting a wooden sign for the gate, and call it the best day they have had in a while.

Air. Both may live in talk and ideas, so feeling settled can mean having something new to think about. It might look like two colleagues who swap books on the train and arrive at work lighter than they left.

Water. Both may go by feeling, and the generosity can be a tender one. It might look like two cousins who each, without arranging it, put aside an old photograph for the other's birthday.

From the sources

What the older sources say (about the same place, not this aspect)

Two older writers put Jupiter on the place of the Lights (the Sun and Moon), though neither singles out the Moon with Jupiter, and the short answer above rests on them.

W. J. Simmonite (edited by John Story, *Complete Arcana of Astral Philosophy*, 1890, rule 431, p. 130) writes of "The greatest sympathies that can exist in two nativities" (birth charts). He describes two charts in which Jupiter or Venus is "upon the place of the Sun, Moon, Part of Fortune" or the Ascendant of the other. The Part of Fortune (a point worked out from the Sun, Moon and Ascendant) and the Ascendant (the sign rising at birth) are other points in a chart. "Upon the place" means the same place, which is a conjunction; calling it that is an editorial reading; he does not use the word. The sentence goes on to a further clause about "the luminaries of the latter", which is not used here.

James Wilson (*A Complete Dictionary of Astrology*, 1819, p. 381, under "Sympathy") writes of the luminaries (the Sun and Moon) and "their mutual position in each others places, or on those of" Jupiter or Venus, which he calls "the best signs of attachment". The sentence begins with the trine or sextile of the luminaries to each other, and its grammar is loose, so it is not clear that it speaks of the conjunction alone. "Attachment" runs on that page from slight attachments to lasting friendship, so it is not read here as any one kind of closeness.

Four limits follow. First, both name Jupiter together with Venus, and the Moon together with the Sun, so neither singles out a Moon with Jupiter; applying their lines to this pair is an editorial reading. Second, neither says which person has which planet, and neither says what the sympathy feels like. Third, both state their readings flatly. Reading them as a tendency, not a promise of how a relationship turns out, is an editorial reading too. Fourth, the other older sources used here do not name Jupiter with the Moon, so nothing from them is used.

Neither passage speaks of a trine, a sextile, a square or an opposition of a Moon and a Jupiter, so nothing in them tells the conjunction from those. The distinction this page draws, that a conjunction reads as fusion or mirroring because it usually joins two points in the same sign, with the same element, is based on the kind of sign a conjunction usually joins. It is an editorial reading, not something the older books say about the Moon and Jupiter. The same goes for everything else on this page: who the Moon person and the Jupiter person are, what each gives and may want, the elements and the sketches, which are illustrations.

Is this you two?

One of you can tell what sort of encouragement the other would welcome, and it may be the sort you would welcome yourself.
A plan has come up between you that neither of you remembers proposing.
A favourite place, class or outing has come to mean "there is room for this" to one of you, and the other knows it.
You can be quiet together and it does not feel like a gap that needs filling.
Now and then your moods have settled at about the same time, and neither of you was sure which of you did it.
Something that makes your world larger and something that makes you comfortable sometimes turn out to be the same thing.
